To all whom it may concern:

Be it known that we, HENRY E. MORLEY and EDWARD GIBSON, citizens of the United States, residing at Detroit, in the county of Wayne, State of :Michigan, have invented certain new and useful, Improvements in Brick-Molds; and we do declare the following to be a full, clear, and exact description of the-invention, such as will enable others skilled inthe artito which it appertains to' make and use the same, reference being bad to the accompanying drawings, and to the characters of reference marked thereon,

which form a part of this specification.

This invention relates to molds for bricks. and the like, and consists in the novel construction and arrangement of parts as "hereinafter' more fully set forth and pointed out particularly in the claims.

The object of the invention is the pro vision of simple and efficient means for molding bricks, blocks and slabs ofplasticmaterial, which may be operated in the manner of a molders flask, and in which a plurality of bricks or the like maybe molded with each operation of'filling the flask, and wherein the construction of the partsis such as to enable the ready withdrawal or discharge of the bricks from the molds through the simple operation of-lifting-the flask.

The invention provides for such a 'con-.

as to enable them to be readily assembled within a confining frame or flask preparatory to receiving the plastic material to be molded, and to permitof the quick releasing of the assembled members to facilitate the rapidremoval of the articles from the mold-when set or driedz The invention consists briefly in the employment of a series of corrugated or undulated flexible strips of metal formed to provide a plurality of integral pocketsor molds of a size to form the thickness, width and length of the bricks to be molded, together with suitable dividing strips for separating the ends of the bricks in connection with a binding frame or flask by which the. parts are held together when assembled and released for disassembling, and by means of which the series of flexible mold strips may drawings which form a part of this specifi cation, and in which Figure 1 is a perspective view of the molds as contained when assembled within the binding frame or flask as they would appear in position for the reception of the plastic substance with which the molds are to be filled. Fig. 2 is afragmentary perspective view of the mold strips broken end of a tie rod as a means for drawing the binding rails of'the frame toward each other. Fig.5 is a longitudinal sectional. view through the mold on dotted line 5,5

- of Fig. 1, with'the mold filled and in the inverted position, and indicating by dotted lines a raised-position of'the dividing strips of the mold. Fig. 6 is a transverse sectional viewon dotted line 6 6 of Fig. 5 showing the binding rails released and the dividing mold strips; Fig. 7 is a longitudinal sectional view through one of the mold strips showing said strip arched downwardly to expand the side walls of the moldsat their open edges and release the bricks from contact therewith when said strips are being withdrawn therefrom.

. Referring to the drawings by the characters of reference marked thereon, 1 represtrips removedfrom position between the 7 sents the mold strips which are preferably of sheet metal and are formed or bent in a corrugated or undulated manner to form a ,plurality of integral successively arranged molds or pockets 2 of a size equal to the thickness, width and length of the'bricks to v be molded. The vertical walls 3 of the pocket's extend at right-angles to the body of the strip forming the horizontal bottom walls 4 of said pockets upon one side of said mold strip and are connected together at rightangles upon the opposite side by horizontaltop walls 5 which abrid e the spaces 6 between the side wallso said pockets, the

I from'after they shall have been molded and sides, renders the strips pliable and capable of being bent in the arc of a circle to expand the openings to said pockets and provide draft or clearance between the side walls tov facilitate the discharge of the bricks thereset to form.

The mold strips are assemblediin series in parallel adjacent relation to each other with the ends of the molds or pockets in separated registering alinement. The end portions of each mold strip 1 are provided with'separated cylindrical sleeves 7, ,preferably formed by bending or rolling the metal upon a' suitable mandrel, and loosely threaded through these sleeves 7 at the opposite ends of said mold strips are tie rods 8 which form pivotal connections for the ends of said strips, and serve to support said strips collectively. The tie rods 8 are exposed between the sleeves 7 of the mold strips at which points the metal is cut away to form hand openings 7 through which .said rods may be grasped for handling the mold,

1 To close the adjacent ends of the pockets 2 of the intermediate mold strips of the series,

between said mold strips atpoints in line with spacing, collars 9 loosely mounted on the rods 8 and interposed between the sleeves 7 to separate said mold strips and permit the entrance of said dividing strips therebetween. Said dividing strips 9 are provided upon 0 posite sides with transribs snugly fit to support and-maintain the side walls 3 of said pockets in arallel alinement and effect aflush connection at the up? per edges of saiddividin strips with the upper surfaces of said br dge walls. The

outermost ends ofthe pockets of the outer-.-

most mold strips of the series are closed by end strips '11 which'lie inline with spacing collars 11 onthe tie rods 8, and are prov vided u on the inner side only with cleats or ribs 12 similar to the cleats 10 of the divid ng strips 9, which enter and lie in the spaces'6.-

at the outer ends of thejpockets of the mold strips to support the side walls at the'ends Ofth pockets oppqsite and in the same manner as the ribs 10 of the dividing strips 9,

The ends of the dividing strips. 9 and end strips 11 are providedwith reduced portions 13- which extend beneath the sleeves 7 and tie rod 8 of the mold strips and are threaded loosely upon a connecting rod .14, the ends of which are slidably received in bosses 15 secured to the inner face of the reduced portions-13 of the end strips 11, and are provided with pins 16 extending through elongated-apertures 17 formed through the walls of said bosses, which limit the end movement of the rod in said bosses and retain said end strips from disengagement with.

saidrod. Mounted loosely upon the connecting rods 14 and extending between the bosses 15 of the end strips 11 and the ends '13 of the dividing strips 9, and also extend ing between the ends of said dividing strips,

are sleeves 18 which serve to space said.

strips apartwith respect to the mold strips and to limit the lateral movement of said- 'so a of the mold strips .by means of binding channel rails 19 which lie in contact with the outer facesof the end strips 11 ,and are provided near their ends with elongated apertures 20 throu h which the ends of the tie rods '8 extend. aid rods are provided at their ends with eyes 21 upon which thebifurcated heads 22 of hand levers 23 are eccentrically pivoted. at 24 and (which are so t. arranged as to present the big sides of the transverse dividing strips 9 are introduced eccentric heads in contact wi h the outer faces of'the binding rails 19 to force said rails toward each other upon the tie rods 8 when said levers are swung into parallel relation with said rails,whereby pressure is applied to draw the mold strips into a close fitting contact with the dividing and end strips to close the ends of the pockets of the molds and to retain the side walls thereof in alinementupon the ribs of the dividing strips so as to insure uniformity in the size and shape'of the pockets preparatory to filling the mold with, the plastic 'substance'to be formed, as shown in Fig. 1.

The parts of the mo plurality" of open rectangular pockets each of which forms a matrix of the size and shape of the brick .to be molded, in which the bridge wall ofth dividing spaces between thepockets lieflush withthe upper edges'of the dividing strips and upon the ribs of Wh1Ch 'S&ld bridge walls are supported in addition to the clamping pressure of the. binding frame, whereby s'aid parts are firmly held a; inst-displacement and may moved about ,odily with said frame.

The frame and molds are placed on a suitable bed plate, not shown, and the plastic substance to be 'molded is introduced by pouring or tamping it into the pockets." The 1d when assembled I and-confined within'th'e binding frame comprisingthe binding rails and tie rods form a surface is then smoothed over ,flush with the upper edges of the dividing strips, and when the material is sufliciently set or hardened a suitable face plate is placed upon the upper surface of the mold and the frame and molds are turned over as shown in Figs. 3, 5, 6 and 7. The eccentric levers 23 are thenswung to the position indicated by dotted lines in Fig. 4" to release the binding rails from contact with the end strips 11, and at the same time releasing the pressure of the mold strips upon the intermediate dividing strips 9. Said strips may then be lifted collectively from the mold by raising the rods 14 upwardly, to the position shown-in Fig. 6 and indicated by dotted lines 1n F1g. 5, the dividing strips passing from the ends of the mold strips and Withdrawing the cleats thereon from within the spaces between said molds, The binding frame carrying the mold strips may then be raised bodily from the face plate bylifting upon the tie rods, whereby the ends of the mold vstrips will be raised somewhat in advance of the bodies of said strips, causing their body portions to sag or bend in the arc of a circle, as indicated in Fig. 7, in which movement the elongated apertures 20 of the binding rails 19 permit the tie rods 8 therein to peated.

move toward each other to rovide for the contractionof the mold strips as'they assume their arched form. This sagging or bending .of the mold strips contacts the spaces 6 at their open edgesbetween the pockets along the inner arc of said mold strips and also expands theside walls of said pockets at their openings along the outer arc of said strips to provide suflicient draft or clearance to release the bricks 26 from contact with said walls and permit the further withdrawal of the mold strips therefrom, as indicated by dotted lines in Fig. 7 th'us discharging the bricks upon the face plate and enabling the mold to be again assembled, set up and the operation re- It will be apparent that a mold constructed in the foregoing manner will be simple, durable and convenient to operate, and will enable the-molding of a. plurality of bricks or other articles of uniform shape and character with each operation, and that the 'pockets of the molds may be varied in shape and dimensions to accommodate varying styles of bricks or blocks and that the pockets u may be provided as shown with a centrally raised portion to form a concavity or depression in one face of the brick or block if desired.

It is obvious that other details of construction may be varied without. departing from the spirit of our, invention, the essential features of which reside in the employment of the flexible mold strips vcarried by a binding frame in connection with the shouldered dividing strips for separating themold strips andfor maintaining the side walls of the mold pockets in vertical allnement.
